addendum: you might have noticed that the current insert_row mentioned on ticket #15965 on the matrix constructed via A = matrix([[1,2],[3,4]]) is actually a rather low-level function using the internals of integral matrices (ie there is some C code involving GMP and flint). This insert_row is t

Dear Jack, The state of linear algebra is very poor in SageMath. Any contribution is very much welcome! SageMath uses a lot of different libraries for linear algebra (I can think of flint, NTL, linbox, scipy, m4ri, arb) as well as some home made (and rather slow) generic implementations. In orde

I am a new user of SageMath, primarily as an alternative to Matlab for verifying linear algebra computations. Something which has become an annoyance is the lack of row and column insertion operations for Matrices. I am a developer (although I have limited experience in Python) and was consider

I must say it's totally unclear to me how not having some default option at certain state breaks something. I'd rather have the mechanics of sharing things online fixed so that the right options are applied for this sharing operations. On Mon, Feb 11, 2019 at 8:05 PM mmarco wrote: > > Is there an

Is there any essential reason why online=False can not work on nbviewer or mybinder? If it can be solved, I think it makes more sense to make it work without breaking the default behaviour when there is no internet available. El lunes, 11 de febrero de 2019, 18:31:33 (UTC+1), Eric Gourgoulhon e

Hi, Strong -1 ! - by making online=True the default, we harm the privacy of users, and we do not even let them the possibility to accept it first. I always feel betrayed by software that go online without my permission. - mybinder or nbviewer are not the primary target for Sage (and by far

I will formally vote for “True”. However I think the default should be "use online if available" and fall back if not. But that implies writing new code to check online availability. François > On 12/02/2019, at 06:31, Eric Gourgoulhon wrote: > > Hi, > > As pointed out in the Free Computatio
